Bone Crusher,
All you need to do is go to the hardware store and buy a "star' washer and put them where ever you have metal to metal contact. Works like a charm.

Did that...still will roll if you put a good amount of pressure on them. Also shouldn't have to go anywhere for parts for something that is supposed to work out of the packaging.
If you want these things to stay put and do not lay them directly on the bracket, they are a poor design as they will not stay...
